6. Peppermint
Peppermint is another ingredient that can stimulate the stomach in a very specific way. This can not only be painful when it reaches the hernia, but it also acts as a diuretic making you more likely to need the toilet.
The problem with a diuretic is that it causes further pain and stimulation to the stomach area, while at the same making you more likely to need to strain and push – two things that really do upset a hiatal hernia.
